ROTATABLE SIGN.

Application filed September 9, 1927. Serial. No. 218,509.

This invention has reference to rotatable signs, and more particularly to signs designed to operate under wind or air pressure.

The primary object of the invention is to provide a sign of this character on which certain advertising matter may be printed to the end that when the body portion of the sign is rotated rapidly by wind pressure, the advertising matter may beread.

A further object of the invention is to construct a sign which will operate by the action of the air or wind passing through the sign, all blades commonly employed in wind and air operated signs being eliminated.

A still further object of the invention is to provide means whereby the speed of retation of the sign may be regulated to meet various requirements. I

Withthe foregoing and other objects in view which will appear as the description proceeds, the. invention resides in the combination' and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a front elevational view of a sign constructed in accordance with the invention.

Figure 2 is a plan view thereof.

Figure 3 is a front'eleva-tional view the front wall of the sign being removed.

Figure 4 is a sectional view taken on line 4-4 of Figure 1.

Figure 5 is a sectional view on line 5-5, Fig. 1.v

Referring to the drawing in detail, the device includes an elongated body portion embodying side members 5, front and rear members 6, the front and rear members 6 having one of theirrespective ends extended over one end of the body portion, the opposite ends of the members 6 being spaced from the opposite ends of the body portion, defining openings 7 through which air may enter the hollow body portion.

As shown, the ends of the members 6 that cover the ends of the body portion are curved as at 8 so that the air entering the body portion will be directed longitudinally of the body portion to accomplish the purpose of the invention, that of. rotating the body portion. 7

, Positioned within the body portion at points adjacent to the ends'thereof, are in clined plates 9 which are spaced from thc members 6 so that air may pass under and over these plates.

Closures such as indicated at 10 are provided at the ends of the body portion and are designed to regulate the size of the openings to vary the speed of rotation of the body portion by increasing or decreasing the amount of air entering the body portion.

As shown, thevdevice is supported at the upper end of the post 11, the post 11 being shown as extending through the central portion of the body, the upper end thereof resting against the bearing 12, to theend that the body portion may be rotated with the least possible resistance.

From the foregoing it will be seen that due to the construction shown and described, a. rotatable sign may be provided, the same being such that it will rotate under air or wind pressure, thereby attracting the attention of persons passing in proximity to the slgn.

I claim:

1. In a sign of the class described, an

elongated hollow body portion, said body portion having an opening formed in the front surface thereof adjacent to one end of the body portion, the rear surface of the body portion having an opening adjacent to the other end of the body portion to permit air to pass through thebody portion, and means for pivotally supporting the body portion so as to be rotated continuously in one direction by a continuous current of air.

2. In a sign of the class described, an elongated hollow body portion having front and rear surfaces, the front surface having an opening adjacent to one end thereof, the rear surface having an opening adjacent to the other end of the body portion, said body portion having end walls curved to direct air longitudinally of the body portion and means for supporting the body portion for rotary movement, so as to be rotated continuously in one direction by a continuous current of air.

3. In a sign of the class described, an elongated hollow body portion having a front surface and a rear surface, the front surface having an opening adjacent to one end thereof, the rear surface having an opening adj aeent to the opposite end thereof to permit air to pass through the body portion, means for regulating the quantity of air passing through the body portion and n leans for pivotally supporting the body portion, so as to be rotated continuously in one direction by a continuous current of air.

4. In a sign of the class described, an elongated hollow body portion having front and rear surfaces, said front surface having an opening adjacent to one end thereof, the rear surface having an opening, adjacent to the opposite end thereof, means for directing air longitudinally of the body portion, and means for pi'votally supporting the body portion, so as to be rotated continuously in one direction by a continuous current of air.

In a sign of the class described an, elongated hollow body portion, said body portion having an opening formed in the front surface thereof adjacent to one end of the body portion, the rear surface of the body portion having an opening formed therein adjacent to the opposite end, of the body portion, plates supported within the body portion and having their free edges disposed adjacent to the openings associated therewith to direct air through the body portion and said body portion having curved end Wall to direct air through the body portion, and means for pivotally supporting the body portion so as to be rotated continuously in one direction by a continuous current of air.

In testimony that I claim the foregoing as my own I have hereto allixed my signature.

SHERMAN S. BENSON.
